Wyoming Capitol dome to be covered for repair until mid-2019


September 12, 2017

CHEYENNE — Needing repair and replacement of failing materials, the Wyoming Capitol dome will be covered with scaffolding and a white scaffold covering until mid-2019 as part of the ongoing renovation work on the Capitol.

The dome scaffolding will start to be installed this week. The scaffolding installation will take between eight and 10 weeks and will cover the dome and the drum (the area just below the dome). Once the scaffolding installation is complete, the scaffolding will be covered with a white covering to help facilitate the repairs and improve safety.

The area that will be covered consists of the gold-leafed dome, lantern, drum, and base. Hands-on investigations of the entire structure have documented punctures, tears, dents, failed seams, corrosion, paint coating failure, significant water leakage, and many missing and loose elements. The damage is mainly from hail and 129 years of life and weather deterioration. Without the repairs, the life expectancy of the dome would be another 15 years.

Extensive work will include replacement and repair of the existing decorative sheet metal, repainting, roof repair, and re-gilding of the dome. The repairs will extend the life expectancy of the dome by over 75 years.

The first phase of the Capitol, completed in 1888, was topped with a copper dome designed in the spirit of the U.S. Capitol dome in Washington, D.C. Later, the gold leaf was applied at specific locations to create contrast and achieve the aesthetic effect of a beacon shining over the skyline of Cheyenne. The dome of the Capitol is 50 feet in diameter at the base, and the peak stands 146 feet above the ground. The 24-carat gold leaf on the dome was added on top of the original copper in 1900 to prevent tarnishing (and it has been retouched five times since). Today the Capitol dome structure consists of a sheet copper dome, which is covered in gold leaf, and galvanized sheet metal lantern and drum.


The Wyoming Capitol Square Project centers on the rehabilitation and restoration of the Capitol, which is a National Historic Landmark. The project includes the rehabilitation and expansion of the adjacent Herschler Building, as well as rehabilitation and expansion of the tunnel that connects the buildings, and relocation and expansion of the central utility plant, serving five state buildings. This complex multi-year project will preserve the historic character of the Capitol, improve public access to the political process, and address needed life safety and building systems deficiencies.
